摘　　要：土壤渗滤法是一种就地污水生态处理技术,它充分利用土壤中的动物、微生物、植物以及土壤的物理、化学特性,能高效去除COD、BOD5以及氮、磷等营养物质,对水源保护和分散型污废水治理的意义重大。就上海虹桥机场围场河典型污染河段进行土壤渗滤法水质生态修复试验,结果表明COD的去除率高达75.8%,TP的去除率高达100%,水体中的溶解氧显著提高,各种有机物也得到相应的降解。同时,结合土壤渗滤法的主要特点及应用前景,对围场河水质生态修复提出了综合性的建议。Soil infiltration treatment is a kind of wastewater ecological treatment in situ,which makes full high removals of COD,BOD5 ,nitrogen and phosphorus,etc. This technique plays an important role on water source protection and decentralized wastewater treatment. This paper was to improve the water quality in typical polluted reach of Weichang River, Shanghai Hongqiao Airport, by bioremediation experiment using soil infiltration treatment technique. The results showed that COD and TP removal rates could reach 75.8% and 100% ,respectively,dissolved oxygen in water were improved significantly,and kinds of organics were removed as well. An integrative suggestion to bioremediation of water quality in Weichang River was proposed from analyzing the main characteristic and application prospect of soil infiltration treatment.
